The more I hear people, news articles, theater promotions, etc. state "The Dark Knight trilogy" the more I wish Batman Begins had a different title...

ala

The Dark Knight Begins....

just saying ...

No. The reason the titles for the films only appear at the end is because it isn't until then that Bruce/Batman earn those titles. Batman officially begins at the end of the first film with the installation of the bat-signal, leading to the title card and he does not become "the dark knight" as the second film defines it until the very end. The Dark Knight Rises will be the same way. Each title in the sequence builds on each other in a similar way that the narratives do. They tell a story in and of themselves.
